Upgrading Work PC

I'm due to get a new PC for work, and I have pretty much free reign on what to get. My budget is around $2,000. I have been looking at Lenovo (specifically the Thinkstation P2 Gen 2) , but am pretty much open to whatever. Size does not matter, and I really only do spreadsheets and email, I could honestly probably get away with spending quite a bit less, but we only replace every 5-8 years so I want something that will last. What is the recommendation for this price point?
